A power supply device includes a conversion module, a plastic case and an inorganic material, and the conversion module includes an input end, a potential ignition source, a conversion circuit and an output end. The input end is configured to receive an input source, and the potential ignition source is configured to suppress a surge of the input source. The conversion circuit is configured to convert the input source into an output source, and the output end is configured to provide the output source to a load. The plastic case accommodates the conversion module, and the plastic case includes an inner surface. The inorganic material is configured between the potential ignition source and the inner surface, and a distance between the potential ignition source and the inner surface is less than 13 mm.

Power supply device

An electrical power conversion device, a function triggering circuit for the electrical power conversion device, and a function triggering method for the electrical power conversion device are provided. The function triggering circuit is coupled between the secondary side of the transformer and the control module and includes a current detection circuit, a delay circuit and a switching circuit. The current detection circuit senses the secondary side of the transformer to generate a detection signal of delay. Before steady-state duty of the transformer, the delay circuit causes an initial level to be higher than an internal level. After steady-state duty of the transformer, the switching circuit selectively generates a function triggering signal according to the detection signal. The function triggering signal is for triggering the control module to carry out an overcurrent protection operation. Therefore, the electrical power conversion device effectuates electrical power conversion precisely and steadily, provides precise overcurrent protection, and achieves low stand-by power consumption.

Electrical power conversion device, function triggering circuit for the same, and function triggering method for the same

A power supply apparatus is provided, and which includes a power conversion circuit, a control chip with soft-start function and a short protection circuit. The power conversion circuit is configured to provide a DC output voltage to a load in response to an output pulse-width-modulation (PWM) signal. The control chip is operated under a DC input voltage, and configured to generate the output PWM signal to control the operation of the power conversion circuit. The short protection circuit is configured to pull-down the level of a soft-start pin of the control chip, so as to substantially/significantly reduce the frequency and duty cycle of the output PWM signal, and then substantially/significantly reduce the current flowing through the shorted load.
